HENRY E. BURGESS, OF BROOKLYN, NEW YORK.

Tun STATES PATENT @Fries1f4 coNCRETE RAILROAD-Tin.

Be it known that I, HENRY E. BUReEss, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of NewYork, have invented new and useful Improvements in Concrete Railroad-Ties, of which the following is a specification.

The present invention relates to improvements in railroad ties, and primarily to de'- tachable raill cushions and fastenings for plastic ties. 'I

In carrying out my invention it is my purpose to provide a plastic railroad tiewith dove-.taile'dpassages arranged at the proper 'track gage and adapted to receive and to beifrictionally contacted by rail supporting cushions, the plastic tie being further provided with substantially U-shaped yo'kes having their ends formed with angularly yarranged flattened plates, the said plates as well as the arms of the yokes adapted to be embedded Within the tie,

i while the connecting portions of the yokes are adapted to lie flush with one ofthe faces of the tie and-to straddle the openings provided by the passages, the said connecting-portions Vof .the yokes being provided with suitable' openings' forA the. reception of headed, securing'elements and whereby the cushions are eli'ectively but removably retained within the passages vand upon lthe tie. With the above recited objects in View and others which will be disclosed as the nature of the invention is more fully -described the improvement resides in the construction, combination and operative arrangement of parts set forth 111 and falling within the scope of the appended claims.

In the drawings, Figure 1 is a perspective view of a tie constructed in accordance'with the"v present invention. Fig. 2 isl anv cnlarged'A sectional view taken upon the line \2-2 of F ig. 1.

Fig. 7 is a perspective view ofthe reinforcing cushion lsustaining member. The tie'compri'ses a substantially 'rectangular bottom 1 constructed preferably of reinforced concrete and the said tie is providedy adjacent its opposite transverse ends with passages 2 and 3, the lower wall lof.

` which being horizontally straight, while the Specification of Letters Patent. Application inea August 2a, 1912. serial No. 716,662.

side walls incline toward each other. IThese? passages are ladapted for the reception of cushion` blocks 4 and 5, the said blocks having their opposite longitudinal sides beveledvll to correspond with the beveled 'side walls provided by the passages, while thelower Vface'of each ofthe cushions is flat to' lie snugly against the straight lower wall of the l passage. The numerals Gand 7 designate metallicv members which are inthe formof substan-` tially U-shaped yokes. The side arms of. each of the members Gand 7 are integrally formed with augularlyfarranged substan'- y70 tially rectangular plates,` 8 and 9. These-v plates project both above and below the4 yoke proper and the said plates as well as` the side-'arms of the yokes are adapted to be -i embedded within: the concrete tie 1 While' 75 the connecting member of each of the yokes;y

is adapted to lie ilush with one'of the faces` of the said tie 1. These connecting mem-f bers, which may be designated'by. the numerals 10 and 11 respectively are each cen'- .so

trally provided withan opening yllthrough which is adapted to. pass a headed screWor bolt 13 which engages with one of the faces` of each of the cushions and sustains thesaid' cushion properly within the ways providedf by the tie. f f Each of the plates 8 andf9 is formed Withfl a plurality of openings 14, the said open ings being adapted to receive retainingelements, such as U-shaped bolts or wires 15,590 as clearly illustrated in Fig. 3 .of the draw-f ing, and the said U-shaped elements' 1'5l also fi fi said cushions may be removed from` thef.- *if passages when worn or otherwise damaged', without `interfering with the tie vproper and? a; a new 4cushion readily substituted therefor. 105

In Figs. 5 to 7, inclusive, I have illustrated a dilferent form of the reinforcing and cushion sustaining member. In these figures `the tie 1 is substantially similar to thatabove described. The tie is provided with the dove-tailed openings for the re ception of dove-tailed cushion bloc-ks. The

eov

cushion blocks sustaining member, as Well the reinforcing element for the tie, which, in this instance, is-desigiiated by thep numeral 20 comprises a single member constructed of Hat metal. The member 2O has its ends substantially rectangular, as at 2l,

` to provide what Vmay be termed the U- above referred to.

shaped yokes. The inside of each of the yokes 21 is adapted to lie 'Hush with one of the faces of the tie l and is provided with an opening 22 for the reception of a securing ,element 23 and which sustains the cushion 24 upon the tie. The outer arms of each of the substantially U-shaped yokes 2l are extended in opposite directions to provide what may be termed plates 25. These plates are formed with a plurality of openings for the reception of substantially U- shaped sustainingmembers 26, the said members being similar to the members 15 The yokes 21 are connectedthrough the medium of a curved body portion 27l which, of coursel` is Feinbedded in the tie during the process of construction of the tie and which, together with the end plates 25 and their U-shapedy retain'- ing'members 26 materially strengthens the tie. The bowed connecting member 27 may `be andpreferably is provided with aplurality of spaced openings 28, each of the said openings being adapted to receive U- shaped reinforcing and sustaining elements 29.

From the above description, taken in connection with the accompanying drawings, the simplicity of -the device, aswell as the advantages thereof,'wi1l, it is thought be perfectl apparent to those skilled in the art to Whici the invention appertains, without further detail description.

LA plastic tie being provided with passages arranged adjacent its opposite transverse. ends, substantially U-shaped yokes having their arms formed with rectangular plates embedded .Within the tie, the connecting member of each of the yokes partially closing the passage upon one lof the faces of the tie, a cushion for each of the passages, and means' for removably connecting the cushions to the yokes.

2. A Vplastic tie having transverse dovetailed passages, spaced suitable tothe track gage, of a pair of cushion rail bearing mcmbers fitted Within and, f rictionally engag in the walls provided by .,.th'e' passages,

su stantially U-shaped yoke members havyokes having its side arms provided withv substantially rectangular angularly arranged plates which project both above rand below theyoke, the side arms as Well as the plates of the yoke adapted to be embedded Within the tie, retaining elements passing through the plates and Within the lastic1 body of the tie, the connectingmem r of y each of the yokes being provided with anr opening and being arranged flush With one of the faces of the tie, a pair of cushion rail bearings arranged .within the passages tot..

frictionally engage therewith and to Contact with the connecting members of thee-yokes and headed threaded members passing through the openings' in the said connect,- ing members of the yolres and engaging the cushion bearings.

4. A plastic tie having-its upper face eri-.1.v larged adjacent its ends 'and said enlarged portions being provided Wit-h dove-tailed depressions, dove-tailed cushions Within the depressions and lying flush with theupper face of the tie, a tie reinforcing and cushion sustaining member. said member having its ends provided with substantially U-shaped yokes, the outer members of which being .iush with one of the faces of thetie, re-

movable mcans for securing this member t0 the cushions, the ends of the yokes having extensions provided with openings,

shaped sustaining members arranged Within the tie, a bowed connecting member for the vol-res, said member being provided with openings, and sustaining members passing through the openings and embedded Within the tie.

In testimony whereof I atiix my signature in presence of two witnesses.
